KENAN THOMPSON & KEL MITCHELL

Then: Like Bynes, Thompson and Mitchell got their starts on the sketch comedy All That before landing their own sitcom, Kenan & Kel, in 1996, and their own movie, Good Burger, based on one of their signature All That sketches. Now: Thompson has taken sketch comedy to the masses as a cast member on Saturday Night Live. Mitchell still acts from time to time, but now reportedly owns and operates several Wendy's restaurants in Mississippi.
